How can I create a temp file with a specific extension with .NET?

I need to generate a unique temporary file with a .csv extension.

What I do right now is

string filename = System.IO.Path.GetTempFileName().Replace(

Based on answers I found from the internet, I come to my code as following:

public static string GetTemporaryFileName()
{       
    string tempFilePath = Path.Combine(Path.GetTempPath(), "SnapshotTemp");
    Directory.Delete(tempFilePath, true);
    Directory.CreateDirectory(tempFilePath);
    return Path.Combine(tempFilePath, DateTime.Now.ToString("MMddHHmm") + "-" + Guid.NewGuid().ToString() + ".png");
}

And as C# Cookbook by Jay Hilyard, Stephen Teilhet pointed in Using a Temporary File in Your Application:

• you should use a temporary file whenever you need to store information temporarily for later retrieval.

• The one thing you must remember is to delete this temporary file before the application that created it is terminated.

• If it is not deleted, it will remain in the user’s temporary directory until the user manually deletes it.
